  2. Piston motion equations - Wikipedia

    en.wikipedia.org/wiki/Piston_motion_equations

    The reciprocating motion of a non-offset piston connected to a rotating crank through a connecting rod (as would be found in internal combustion engines) can be expressed by equations of motion. This article shows how these equations of motion can be derived using calculus as functions of angle (angle domain) and of time (time domain).

  3. Piston - Wikipedia

    en.wikipedia.org/wiki/Piston

    The connecting rod is attached to the piston by a swivelling gudgeon pin (US: wrist pin). This pin is mounted within the piston: unlike the steam engine, there is no piston rod or crosshead (except big two stroke engines). The typical piston design is on the picture. This type of piston is widely used in car diesel engines. According to purpose ...

  4. Slider-crank linkage - Wikipedia

    en.wikipedia.org/wiki/Slider-crank_linkage

    For this reason, the in-line slider-crank mechanism produces balanced motion. This balanced motion implies other ideas as well. Assuming the crank arm is driven at a constant velocity, the time it takes to perform a forward stroke is equal to the time it takes to act a reverse stroke. The crank moves in only one direction, provided the position ...

  5. Reciprocating motion - Wikipedia

    en.wikipedia.org/wiki/Reciprocating_motion

    The piston moves in a reciprocating motion, which is converted into the circular motion of the crankshaft, which ultimately propels the vehicle or does other useful work. [citation needed] The reciprocating motion of a pump piston is close to but different from, sinusoidal simple harmonic motion. Assuming the wheel is driven at a perfect ...

  6. Reciprocating engine - Wikipedia

    en.wikipedia.org/wiki/Reciprocating_engine

    The piston is moving down as air is being sucked in by the downward motion against the piston. Compression: This stroke begins at BDC, or just at the end of the suction stroke, and ends at TDC In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves ...

  7. Connecting rod - Wikipedia

    en.wikipedia.org/wiki/Connecting_rod

    A connecting rod, also called a 'con rod', [1] [2] [3] is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. [4] The connecting rod is required to transmit the compressive and tensile forces from ...

  8. Crankshaft - Wikipedia

    en.wikipedia.org/wiki/Crankshaft

    A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, [1] that are driven by the pistons via the connecting rods. [2]

  9. Crank (mechanism) - Wikipedia

    en.wikipedia.org/wiki/Crank_(mechanism)

    Reciprocating piston engines use cranks to convert the linear piston motion into rotational motion. Internal combustion engines of early 20th century automobiles were usually started with hand cranks (known as starting handles in the UK), before electric starters came into general use.
